Holding system

The vacuum collection system shown above is primarily used for the holding of sewage while transiting restricted waters with ultimate discharge at sea or to a shore side connection. This system can also be interfaced with a

TYPE II wastewater treatment system or an atmospheric holding tank.

Column tank system

Where elevation and vessel design permits, the column tank system allows direct connection of the vacuum system to a treatment plant or atmospheric holding tank without the need for sewage pumps and controls.

Mini column tank system

For smaller installations and where height is limited, the mini column system allows direct connection of the vacuum system to a treatment plant or atmospheric holding tank.

Advantages of vacuum... tough to beat

Three pint flush offers 90% reduction in sewage volume and holding weight.

Small diameter piping (2") results in lower material and labor costs.

No slope piping allows wide flexibility in piping design and upward flushing capability.
